Specification of letters Patent.

' Patented Aug. 6,1912.

Application filed December-'5, 1910. Serial No. 595,705.

To all'whom it may concern;

-Be it known that I, GEORGE W. BAKER, a citizen of the United States, residing at Colmesneil, in the county of Tyler and State of Texas, have invented anew and useful Syrup-Pan, of which the followlng is a specification.

' It is the object of this invention to 'pro- I vide a pan adapted to -be used-in boiling down sap and the like, the pan being so constructed that any sediment which Is in the material being boiled down, will be prevented from flowing- .toward the outlet of the pan.

Another object of the mvention is .to provide apan in which the process may be carried forward without endangering the material through burning.

Another-object of the invention is to vide a'pan so constructed that when the is applied thereto, the circulation in the pan,

- caused by the application of the heat there- .view which'will appear as the description to, will tend tohold back any sediment which is in the material being treated in the 25 p an. r

With the foregoing and other objects in roceeds, the invention resides in the-.comination and arrangement of-parts and in the details of construction hereinafter described and claimed, it being understood that chan es in the precise embodiment of invention ereindisclosed can be made with- 1n the scope of what isclaimed'without departing from the spirit of the invention.

In the drawings, Figure 1 is a top plan; Fig. 2 is a side elevation parts being broken away; Fig. 3 is atransverse section on the line A-B of Fig. 1; and Fig. 4 is a transverse section on the line C-D of Fig. 1.

The an 1 includes a bottom 2 and a c1rcumscribing wall 3, the wall 3 being curved at one end as denoted by the numeral 4 and being rectangularly disposed at the other end, as denoted by the-numeral 5.

. A longitudinally extending division plate 6.is provided, and this division plate 6 is in v contact with the bottom 2 of the pan, and with the end wall 5 thereof. At one end,

however, the division plate 6 is spaced at some distance from the curved end wall 4. A pair of plates 7 are secured at their inner ends to the division plate 6, and at their outer ends to the curved end wall 4 of the San. These plates 7 serve as braces for the ivision plate 6. By referring to Fig. 2 of proeat-

ed, the bafiie plates 12 'baflie plates 14 project the drawing, it will be seen that-the brace plates 7 at their lower edges, are spaced, as

denoted by the numeral8, from the bottom 2 of the pan 1, so that the sap maypass beneath the plates. '1"

A transverse barrier plate 9 is provided, this plate 9 being in cont-act with the botpan, and with the division plate 6. The longitudinally extended division plate 6 serves to separate the pan 1- into compartments A and B, the compartment B, in its turn, be-- ing sub-divided into compartments C and D by the transverse barrier plate 9. In the transverse barrier plate 9 there is an opening 10, forming, a communication. between the compartments C and D, this opening 10 being controlled by a valve 11, of any desired construction. 1

In the compartment D, a plurality of transverse baflie plates 12 and 14 are mounttom 2, of the pan, with one side wall of the projecting inwardly from one side wall of the pan, while the outwardly fromthe longitudinally extending division plate 6. Located adjacent the end wall .5 of the pan is an inlet 15, communicating with the compartment A. Located upon the opposite side of the longitudinally extended division plate 6, and communicating with the com partment D is an outlet 16, having a valve 25.

The, invention further includes a heater 17 the 'rate whereof is denoted by the .nu- Ineral 1 the stoke doors by the numeral 19, and the stack by the numeral 20.

The operation of the device is as follows: The compartments A and C are filled with sap, to the depth: of, say, two or three inches, the compartment D being'filled with water, to prevent the pan from burning, the valves 11 and 25 being closed. A fire is then built in the heater 17, upon the grate 18, should a grate 18 be employed. In any event, the heat will be greater-adjacent the stoke doors 1%) than adjacent the stack 20. .By this construction, any sediment. which is in the sap in the compartments A and C will be forced backwardly toward the end Wall 5, owing to the fact that the i-naxinmm degree of heat. is applied to the pan adjacent the end wall 4. The sediment. accumulating about the inlet 1;), may be skimmed oft from time to time.

After the sap has been boiled sufiicientl in the compartments A and C, so that it 18 :and C.

partly concentrated, the process being continued until all of the sediment in the sap has accumulated about the inlet 15, the valve 25 in the outlet 16 is opened, permitting the water in the compartment- C to flow away.

The valve ll is then opened,-permitting the partially concentrated sap in thecompartments A and G to flow into the compartment- D, whereupon the valves 11' and 25 are closed, and a further supply of fresh sap is admitted to the compartments A Thesap', beingthoroughly skimmed by the-process .above mentioned, and being im- .sap may warrant.

The device is so constructed that one per-' son may handle the same, unaided, a highly concentrated product, free from sediments,

being produced, with a minimum amount of attention during the operation.

' Owing to the fact that the wall 4 is curved as shown at 22, the sediment in the sap will be-deflected rearwardly, and be prevented from finding -lodgment in the end of the pan" to which the. maxi-mum degree of heat is applied.

After the sap has passed from the compartment A into the compartment G, that portion of the division plate6 which protrudes beyond the barrier 9 toward the ,curved end wall 4, will serve to prevent the sap from which the sediment has been removed, from finding its way backward,to

any appreciable extent, into the compartment A.

Having thus described the inventiornwhat is claimed is An evaporatorcomprising a pan; a 1on gitudinallylextended division plate secured to one end wall of the pan and spaced from the other end wall'of the pan, the last named end wall being curved; plates spaced from the bottom of the pan and diverging from the vfree end of the division plate into union with the curved end Wall of the pan, said plates being radially disposed with respect to the curved end wall; a transverse barrier connecting the intermediate portion of the division plate with one side wall of the pan, the barrier being provided with a valvecontrolled passage; an inlet for the pan, and

an outlet therefor, located upon opposite sides of the division plate, and both located adjacent the first named end wall of the pan; and means for supplying a maximum degree of heat beneath one end of. the pan i only and adjacent the longitudinal center only of the pan, adjacent the rounded end I wall, whereby ebullition will take'place ad jacent the rounded end of the pan only,

thereby to drive backwardly, away fromthe free end of the division plate, floating material in the liquid which is being. concen trated.

In testimony that I claim the foregoing as my own, I-hav'e hereunto afiixed my. signa ture in the presence of two witnesses.
